JOURNAL-BEARING.

To all whomz't may concern Be it known that I, SAMUEL J. SHARP, acitizen of the United 'States of America, and resident of Wheeling,county of Ohio, and Estate of West Virginia, have invented certain newanduseful Improvements in J ournal-Bearings, of which the following isaspecification.

This invention relates broadly to journal bearings, and moreparticularly to a bearing of a self-luln'icating type.

The chief object of the invention is to provide an eiiicientself-lubricating bearing for the necks or spindles of rolls of thegeneral character employed in the open soaping and washing machines oftextile plants and print works.

A further object is to provide a simple, durable and comparativelyinexpensive journal bearing structure which embodies means whereby thebearing is at all times kept adequately lubricated, which is extremelyeconomical in the use of lubricating oil, which effectually guardsagainst loss of the lubricant through leakage, and which prevents theoil, from draining from the bearing either into contact with the roll orinto the water of the soaping machine.

lVith these and other important objects in view, the invention residesin the features of construction, arrangement of parts and combinationsof elements which will hereinafter be fully described, reference beinghad to the accompanying drawings, in which Figure l is a side elevationof the invention illustrating the application thereof;

Fig. 2 is a central longitudinal section of the invention; and- Fig. 3is a view of the same partly in inner end elevation and partly intransverse section.

Referring to said drawings, in which like designating charactersdistingulsh like parts throughout the several views-- 1 indicates thebody of a bearing support having a base 2, preferably integraltherewith, for mounting in a suitable position, as upon a side 3 of theframe of an open soaping machine of the type commonly employed intextile plants and print works. Formed in said body 1 is a chamber orreservoir 4 for a lubricant. Rising above the reservoir at oppositesides are lateral walls 5, integral with said body 1, which have theirinner faces inwardly and down- Specification of Letters Patent.

has therein a longitudinal channel 8 adapted for the reception of thespindle or journal 9 of a shaft or roll, as the roll 10 of a soapingmachine. The under side of said block is shouldered at its ends andlateral edges to seat more or less snugly within the upper part of thereservoir for prevpntliing relative shifting movement of said Extendingupward through the bearing block 7 at an approximate tangent to thechannel 8 thereof and opening into the latter at or slightly above theplane of the axis of the journal 9 when the latter is seated in saidchannel is a bore or passage 11 in which is received the body portion ofa suitable wick 12 which has its lower end depending within thereservoir and its upper end protruding slightly from the upper end ofsaid passage so as to contact with the journal 9.

As is obvious, the wick 12, through capillary action, conducts lubricantfrom the reservoir and deposits the same upon the journal with which itsupper end is disposed in wiping contact. Excess lubricant conducted asaforesaid into the channel 8 of the pillow block 7 drains back into thereservoir, the outer end of said block having therein a drain channel 13in open communication at its upper end with said channel 8. A similardrain channel may also be employed at the inner end of said block, but Iprefer that the inner end face of said block shall be slightly inclinedin a clownward and inward direction, as is best shown at 14 in Fig. 2.Obviously, oil draining from the inner end of the channel 8 will followthe inclined face 14: and return to the reservoir. It will be noted thatthere can be absolutely no leakage or waste of lubricant and,consequently, that not only can no oil find access from the bearing tothe water of the soaping machine, but also a condition of Inussiness inthe bearing is avoided.

and terminat- I ing upward therethrough and opening into the channelthereof adjacent to the level of the axial line of the latter, a supportdisposed in underlying relation to saidpillow block and having alubricant reservoir therein, said block being removably seated upon saidsupport and having its under side extending within the top of saidreservoir for preventing relative shifting movement, the ends of saidblock beingshaped to permit drainage of lubricant from said channel tothe reservoir, and a wick disposed in the bore of said block, said wickhaving its lower end depending within said reservoir and its upper endprotruding into said channel.

2. A self lubricating journal bearing comprising a pillow blockchanneled for the reception of a journal, said block having a boreextending upward therethrough and opening into the channel thereof, asupport upon which said movably seated, said support having a lubricantreservoir therein beneath said block, the ends of said block beingshaped to permit drainage of lubricant thereover from said channel tothe reservoir, and a wick disposed in the bore of said block, said wickhaving its lower end depending within said reservoir and its upper endprotruding into said channel.

In testimony whereof I afliX my signature in presence of two subscribingwitnesses.
